Data lake consulting

Data lake consulting: one governed place for raw and curated data

We design data lakes that keep raw data cheap to store but still easy to find, trust and query, so analysts and data scientists stop copying extracts around.

  • Lakehouse designs on S3, ADLS or Google Cloud Storage
  • Open table formats such as Delta Lake and Apache Iceberg
  • Catalogues, lineage and access policies
  • Zones for raw, cleaned and business-ready data

What we help with

Architecture

Storage layout, file formats, partitioning and naming conventions agreed up front.

Ingestion

Batch and streaming loads from applications, SaaS tools and files.

Governance

Data catalogue, ownership, classification and fine-grained permissions.

Query layer

Engines such as Athena, Synapse, BigQuery or Databricks SQL for analysts.

Avoiding the data swamp

A lake becomes a swamp when nobody knows what a dataset means or whether it is current. We attach an owner, a description and a freshness check to each curated dataset, and we keep raw zones out of reach of casual reporting.

How an analytics engagement runs

  1. Step 1

    Questions first

    We agree the decisions the data should support and the measures that matter.

  2. Step 2

    Data review

    We profile your sources, note quality issues and confirm what is feasible.

  3. Step 3

    Build in slices

    Pipelines, models and reports are delivered one subject area at a time.

  4. Step 4

    Hand over

    Documentation, access controls and training so your team can run and extend it.

Frequently asked questions

Data lake or data warehouse?

Many organisations need both, or a lakehouse that combines them. We recommend based on your data types, users and budget.

Can you work with the tools we already pay for?

Yes. We usually build on your existing cloud, warehouse and BI licences, and recommend new tools only when there is a clear gap.
